Hi all, some one can point me some suggestion on choosing CWDM OADM (brand and model)? I need to setup a PtP link on my university campus over our fiber link current used for ethernet. Maybe I can mode on ring based topology in the next. I have no idea, and price are very different on the market today. A max of 8 or 16 ports 3/4 RU is good for me. Please help Mark
